HYDROCARBON-BU RN ER.

SPECIFICATION forming part of Letters Patent No. 738,509, dated September 8, 1903.

Application filed June 6, 1902. Serial No. 110,477. (No model.)-

To all whom, it ntcoy concern):

Be it known that I, ISAAC P. WILSON, a citizen of the United States, residing at New York, in the borough of Manhattan, county and State of New York, have made a new and useful Invention in Hydrocarbon-l3urners, of which the following is a specification.

My invention is directed particularly to improvements in hydrocarbon-burners de- IO signed for generating heat under steam-boilers, in furnaces, or analogous places; and it has for its object to provide a burner of the type indicated which shall eifectually vaporize the hydrocarbon oil and mix the vapor with a supply of air and steam in such manner that the best heating results are obtained.

Myinvention will be fully understood by referring to the accompanying drawing, which is a sectional view taken through the operaac tive parts thereof, asteam-boiler being shown in side elevational view with the burner applied thereto.

Referring now to the drawing in'detail for a full and clear understanding of the invention, such as will enable others skilled in the art to construct and use the same, B represents a steam-boiler of wellknown type, supported above a fire-box having the usual grate-bars G.

0 K represents a metallic casting'having four inlets for receiving, respectively, an air-supply-pipe A through a'screw-threaded junction-pipe J, an oil-supply pipe 0, located below and in alinement with the before-mentioned air-pipe A, said oil-supply pipe being adjustably connected to the casting K by a screw-plug, a steam-supply pipe S, located at right angles to the before-mentioned pipes and secured to the casting K by a screw-plug, and a fourth or conveying pipe P, which surrounds the innerend of the steam-supply pipe S and is located within the fire-box and constitutes a means of support for the entire burner and also a mixing-chamber, as well as 5 a means of conveyance for all of the combustible gases when intermingled before ignition.

N is a nozzle upon the inner end of the steam-pipe S.

The air-pipeAis provided at its lower end with a damper D, which may be drawn laterally for the purpose of regulating the sup ply of air. 7

E is a perforated bottom or partition of wire-gauze or similar material, and C is a supply of broken or granulated carbon or equivalent material for regulating the flow of air therethrough and overcoming or avoiding the noise usually accompanying such apparatus. The inner end of the oil-supply pipe 0 is adjustable to and from the steamsupply pipe S for the purpose of bringing the supply of oil into more or less close proximity to said steam-pipe.

H is a baffler having perforations I, made, preferably, of fire-clay and baked in the usual manner, said baffler being supported by the grate-bars G and located directly in the path of the outiiowing intermingled gases from the pipe P, its function being when heated to white heat to aid in the complete combustion of all of the carbonaceous matter in the fuelsupply.

The operation is as follows: The steam from 7 any source of supply (not shown) is admitted through the steam-pipe Sand allowed to flow in the direction of the arrow through the outlet of the nozzle N. After the steam-pipe becomes sufficiently heated a hydrocarbon oil, such as petroleum, is admitted through the oil-pipe 0 from below and air from the airpipe A above in the direction of the several arrows indicated. As the oil comes in contact with the heated steam-pipe S it is Vapo' rized, and the vapors thereof are intermingled with the infiowing air through the pipe A as it passes downward through the comminuted or divided carbon C and cone-shaped extension. Ultimately these intermingled gases are effectually mixed with the outliowing 9o steam at the nozzle N. Cotton-waste W or similar material, saturated with oil, is then ignited and thrown into the fire-box above the grate-bars G at the point shown, and the gases emitted from the conveying-pipe Pare 5 thus ignited. As the combustion continues the perforated ba'filer l-I becomes heated to a white heat and materially aidsin effectually consuming all of the combustible elements emitted from the pipe P. WVhen the combus tion reaches the highest point, the flame ascends in the manner shown and passes, as

' to the uptake.

indicated by the curved arrows, through the lines in the boiler B and ultimately out over the top thereof in the direction of the arrows (Not shown.)

With such an arrangement of structural apparatus I am enabled to obtain the best possible results by reason of the fact that theintermingled air and vapors of the oil as they are heated by the steam-pipe S before they reach the mouth of the nozzle N enables me to effect the best possible intermingling of said gases with the steam, so that as the intermingled gases and steam are emitted from the pipe P they are in the very best possible condition to support combustion. This, together with the beneficial result attributable to the heated baffler H, enables me to effectually consume all of the combustible carbonaceous elements of the gases and to obtain the highest heat attainable therefrom.

I am aware that attempts have heretofore been made to create sufficient heat with hydrocarbon-burners for the purpose of generating steam beneath boilers and in kindred places by combining air, the vapor of carbonaceous oil, and steam, and I make no claim hereinafter, broadly, to a hydrocarbon-burner for effecting such results.

' I am aware that a hydrocarbon-burner has heretofore been devised in which oil, air, and steam are combined in the manner disclosed in United States patent to S. A. Hill, No. 85,663, granted January 5, 1869, and I make -no claim hereinafter broad enough to include such a structural apparatus. My most generic claim is directed to a hydrocarbon-burner in which the oil and the air are brought simultaneously into contact with a heated steam-pipe and on opposite sides thereof and the gases resulting from the action of the heat upon the air and the oil are united with the steam at the exit end of the steam-pipe in a substantially concentric surrounding conveying-pipe and ignited at the outer end of said'conveying-pipe, such an arrangement making it possible to effectually vaporize the oil and to thoroughly in termingle the air, oil, and steam at the point of ignition.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. A hydrocarbon-burner having a steampipe in combination with an air-inlet pipe and an oil-pipe located on opposite sides of said steam-pipe; together with a conveyingopposite sides of the steam-pipe, the free end.

of the steam-pipe being located at a point near the outlet of the conveying-pipe and the arrangement of all of the parts such that the vapor of the oil is intermingled with the air and subjected to the heat of the steam-pipe throughout the inclosed length thereof, substantially as described.

3. In a hydrocarbon-burner a conveyingpipe having one end located beneath a boiler or other surface to be heated, the other end' thereof being secured to a means of support and operatively connected with an air-pipe, a steam-pipe and an oil-pipe, the air and the oil pipe being located on opposite sides of the steam-pipe so that the air and the oil will come into contact with said pipe at the same instant of time and be subjected to the heat thereof throughout its entire length; the free end of the steam-pipe being provided with a nozzle located at a point near that end of the conveying-pipe which is situated beneath the boiler or surface to be heated, substantially as described.

4:. A hydrocarbon-burner embracing a sustaining or supporting casting K having four inlets; a conveying-pipe and a steam-pipe secured thereto, the latter within the former so as to constitute a mixing-chamber which wholly surrounds the steam-pipe, together with an air-pipe and an oil-pipe secured on opposite sides of the steam-pipe, the free end of the latter being provided with a nozzle located near the free end of the conveying-pipe, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ISAAC P. WILSON.
